3 Questions
What is the main purpose of a nuclear reactor?
To create energy
What is the role of the control rods in a nuclear reactor?
To absorb neutrons
What is the purpose of the cooling water from the cooling tower in a nuclear reactor?
To circulate the cooling water from the cooling tower to the condenser and heated water from the condenser back to the cooling tower
Study Notes
- A nuclear reactor uses nuclear fuels to create energy.
- The nuclear fuel is unstable and can be converted into radioactive materials.
- In nuclear fission, the slow moving neutrons are bombarded on the atoms of the nuclear fuel.
- The heavy nucleus of nuclear fuel like uranium is split into two or more lighter nuclei.
- The reduced mass converted into enormous energy.
- The energy released is taken away by primary coolant.
- Parts of a nuclear reactor include the moderator, control rods, external shield, heat exchanger, generator, and condenser.
- The moderator slows down the neutrons, the control rods absorb neutrons, and the external shield protects people from radiation.
- The heat exchanger converts the heat from the nuclear reactor into steam, the generator converts the mechanical work of the turbine into electrical energy, and the condenser condenses the steam.
- The feed pump extracts the condensate from the condenser and feeds it back to the heat exchanger, and the cooling water from the cooling tower circulates into the condenser.
- The condenser water circulating pump circulates the cooling water from the cooling tower to the condenser and heated water from the condenser back to the cooling tower.
